A cutting machine can include a cutting machine body that is movably supported above a table and capable of vertical movement, the cutting machine body can be positioned at an upward waiting position and a lower end position. The cutting machine body can include an auxiliary cover positioned around a portion of a blade and including a projection. When in the upward waiting position the auxiliary cover is not able to move upward because of the position of the projection, and in the lower end position the auxiliary cover is able to move upward.

The present invention pertains to the technical field of shields, and in particular, relates to a stage dedusting shield for a dust-free table saw, comprising: a shield assembly and a dust suction cover assembly; wherein the dust suction cover assembly is mounted between a follower board and a rear portion of a saw blade and is fixed by the follower board and a rear rocker arm. The dust suction cover assembly comprises a dust suction cover and a rear rocker arm sleeved onto the exterior of the dust suction cover, wherein the dust suction cover and the rear rocker arm are movably connected to a dust suction cover torsion spring via a dust suction cover rotary pin.

A cutting device for a machine tool, suitable for mounting on the spindle support structure of a machine tool for processing and cutting materials, incorporates suckers able to cause the device to adhere to and be fixed to the materials being machined. Further, a cutting head having a protection device with incorporated suckers, a cutting spindle having a protection device with incorporated suckers and a machine for machining the materials, having a cutting spindle incorporating suckers.

Table saws with safety systems are disclosed. The safety systems detect and react to dangerous conditions, such as contact between the blade and a person. The table saws may include a switch, a first light that illuminates to indicate the safety system is operable, and a second light that illuminates to indicate that the safety system is inoperable. The switch may not power the saw when switched on if the second light is illuminated.

The invention relates to apparatus for providing for the powered cutting of a workpiece, typically in the form of a planar or sheet material. The apparatus includes a rotatable blade to cut the workpiece and the blade is mountable such as in a first mode of use to be capable of being held in a fixed position in which the workpiece is moved past the blade, and a second mode of use in which the blade is moved with respect to the workpiece to cut the same. The workpiece is mounted on a base and the blade is mounted with respect to the base via one or more slide members.

A circular saw, in particular hand circular saw, is disclosed. The circular saw has a workpiece support surface, a saw blade and a protective cover, which covers the saw blade in a region above a workpiece to be processed. The protective cover has such a geometry and position with respect to the saw blade that a straight line, which originates from the first deflection of a tangent applied at the intersection of the saw blade circumference with the workpiece support surface from the protective cover encloses an angle of up to 30, in particular up to 20, with a line perpendicular to the workpiece support surface.

A push stick for a table saw and a table saw with the push stick are provided. The push stick includes a gripping possibility for a machine operator at its operator-side end. A workpiece engagement notch is formed at the push stick's workpiece-side end. The notch includes a push surface facing in an intended feed direction of the workpiece and a holding-down surface protruding therefrom at the top under a preferably right angle. The push stick includes a detection device which detects whether the push surface and the holding-down surface lie flat against the workpiece. The push stick further includes a signaling device which emits a flat contact signal when the detection device has detected a flat contact of the push surface and the holding-down surface on the workpiece. The signal therefore signals whether the push surface and the holding-down surface lie flat against the workpiece.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and an upper blade guard covering an upper portion of the saw blade. The miter saw also includes a cut line indicator coupled to the upper blade guard. The cut line indicator includes a light source, a cover positioned between the saw blade and the light source, a housing in which the light source is positioned, a rib coupled to one of the cover or the housing, and a first slot defined in the other of the cover or the housing. The cover includes a second slot through which light from the light source passes to illuminate opposite sides of the saw blade and a work piece supported upon the base assembly, thereby casting a shadow of the saw blade onto the work piece. The rib is receivable within the first slot to align the second slot with the saw blade.

Table saws and table saws designed to implement safety systems that detect contact between a person and a dangerous portion of the saw are disclosed. Table saw components, mounting systems for table saws, and table saw attachments are also disclosed. One embodiment may include a first clamp surface, a second clamp surface spaced apart from the first clamp surface so that a base portion of a riving knife or splitter can be placed between the clamp surfaces with the opposing sides of the base portion generally parallel to the first and second clamp surfaces.
